A bit interleaving method involves applying cyclic block permutation process to a QC LDPC codeword made up of N cyclic blocks each including Q bits, a bit permutation process to the codeword after the cyclic block permutation process, and dividing the codeword, after the bit permutation process, into a plurality of constellation words each made up of M bits, the codeword being divided into N / M sections, each constellation word being associated with one of the N / M sections, and the bit permutation process being performed such that each of the constellation words includes one bit from each of M different cyclic blocks associated with a given section. |
